(RHSA-2004:045) gaim security update

Gaim is an instant messenger client that can handle multiple protocols.

Stefan Esser audited the Gaim source code and found a number of bugs that
have security implications. Many of these bugs do not affect the version
of Gaim distributed with version 2.1 of Red Hat Enterprise Linux.

A buffer overflow exists in the HTTP Proxy connect code. If Gaim is
configured to use an HTTP proxy for connecting to a server, a malicious
HTTP proxy could run arbitrary code as the user running Gaim. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0006 to this issue.

An integer overflow in Gaim 0.74 and earlier, when allocating memory for a
directIM packet for AIM/Oscar, results in heap overflow. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0008 to this issue.

Users of Gaim should upgrade to these erratum packages, which contain
a backported security patch correcting this issue.

Red Hat would like to thank Steffan Esser for finding and reporting these
issues and Jacques A. Vidrine for providing initial patches.
